SCA: security update for github.com/open-feature/flagd/flagd (GHSA-rmrf-g9r3-73pm)

high Tenable Self-Hosted Container Security Plugin ID 438613

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - flagd is a feature flag daemon with a Unix philosophy. Prior to 0.14.2, flagd exposes OFREP
 (/ofrep/v1/evaluate/...) and gRPC (evaluation.v1, evaluation.v2) endpoints for feature flag evaluation.
 These endpoints are designed to be publicly accessible by client applications. The evaluation context
 included in request payloads is read into memory without any size restriction. An attacker can send a
 single HTTP request with an arbitrarily large body, causing flagd to allocate a corresponding amount of
 memory. This leads to immediate memory exhaustion and process termination (e.g., OOMKill in Kubernetes
 environments). flagd does not natively enforce authentication on its evaluation endpoints. While operators
 may deploy flagd behind an authenticating reverse proxy or similar infrastructure, the endpoints
 themselves impose no access control by default. This vulnerability is fixed in 0.14.2. (CVE-2026-31866)

Solution

Update the github.com/open-feature/flagd/flagd library and its related packages to version 0.14.2 or later.
